Dynamic vehicle weighing system and method based on edge calculation

Abstract

The invention discloses a dynamic vehicle weighing system and method based on edge calculation, and the method comprises the steps: verifying the authenticity of a vehicle from the aspects of vehicle identity information, license plate information, vehicle actual physical parameters and the like through the arrangement and cooperation of an axle load scale, an annular coil sensor group, an RFID recognizer and a high-speed camera module; three axle load weighing groups are arranged and each axle load weighing group is configured differently, and calibration, correction and compensation are combined, so that on one hand, the detection precision of the dynamic vehicle weight is ensured, and on the other hand, the illegal behaviors of escaping and influencing the detection result, such as vehicle turning, are effectively avoided; an edge computing technology is introduced into vehicle weighing detection, so that the system response capability and the information interaction efficiency are greatly improved; a static weighing platform matched with a vehicle dynamic weighing system is arranged, interconnection is carried out through edge cloud, a humanized scheme of pre-inspection and re-inspection is provided, and the satisfaction degree of vehicle owners is improved.

Description

technical field [0001] The invention belongs to the application of edge computing technology in the field of traffic control, especially the field of vehicle overweight detection, and relates to high-speed unmanned dynamic weighing detection and static re-inspection related systems and specific methods of vehicles. Background technique [0002] In recent years, with the rapid development and take-off of China's economy and the rapid expansion of industrial industries, the volume of logistics has been increasing exponentially, and the most important mode of transportation in logistics is expressway transportation. Therefore, for the consideration of benefit maximization, overloaded vehicles are also showing an increasing trend. In the long run, the operation of such overloaded vehicles will inevitably cause damage to roads, bridges, etc., which will become the main cause of shortening the durability of roads, so there is a problem of increasing maintenance costs for roads.

Problems solved by technology

However, this method requires vehicles to stop, the detection efficiency is low, and it will significantly affect the traffic efficiency

[0004] In order to solve the above problems, a dynamic vehicle weighing system and method have been developed, but the dynamic vehicle weighing in the prior art generally has the following problems: first, the measurement method is single, and the vehicle is only weighed and cannot be compared with the vehicle. The effective association of other information leads to evasion phenomena such as vehicle forgery; second, the measurement accuracy is not enough. The weighing of high-speed vehicles is already a problem, and relying only on the accuracy and performance of the load cell itself is far from being able to meet the complex requirements. Changeable on-site environment; third, some experienced drivers will reduce the measured value of the load cell by means of changing directions, and this phenomenon is also the most difficult problem to solve in actual measurement; fourth, the measurement data and results need to be Continuously uploading to the remote server, the stability of data transmission and the timeliness of judgment results cannot be effectively guaranteed; fifth, for the situation judged as overloaded by the system, the car owner cannot express objection and revise the judgment in a timely and effective manner
